Description
R223C16 16-channel relay board with an RS232 DB9 female interface for serial port control. It is powered by DC 12V (voltage range 9-13V) and draws about 18mA in standby, so it runs on low-voltage DC only and is not connected to mains supply. It supports AT commands and 8-byte commands, which are recognized automatically without switching, with a maximum AT command delay of 9999 seconds. Eight working modes are available: open, close, jog, self-lock, interlock, delay, all open and all close. Maximum load is 10A at 250VAC, 125VAC, 30VDC, 28VDC or 12VDC.
